SPECIFICATION forming part of Letters Patent No. 771,096, datedSeptember 27, 1904. Application filed January ll, 1904. Serial No. 188,571. No model.)

To @ZZ whowt t 7am/,y concern:

Be it known that I, EUGENE C. RICHARD, a citizen of the United States, residing at Detroit, in the county of IVayne and State of Michigan, have invented certain new and useful Improvements in Carbureters, of which the following` is a specification, reference being had therein to the accompanying drawings.

The invention relates to carbureters, and has more particular reference to aconstruction intended for use in explosion-engines.

The invention consists in the peculiar construction, arrangement, and combination of parts, as hereinafter set forth.

In the drawings, Figure l is a longitudinal section, partly in elevation. Fig. 2 is acrosssection, and Fig. 3 is a plan.

A is a receptacle for the oil, provided with an inlet-conduit B, which is controlled by a valve C, attached to a float D Within the receptacle, the arrangement being' designed to 'maintain substantially constant level of oil within the receptacle.

E is an outlet-conduit from the receptacle, which connects with a vertical nozzle F, having a controlling needle-valve G.

H is a plug-valve in the nozzle above the needle-valve G and adapted to variably restrict the passage in the nozzle.

I is an air-conduit into which the end of the nozzle F is directed, said conduit leading to the inner valve of the explosion-engine. The lower end of this conduit I is connected with a horizontally-extending casing J, having the inlet-tube K, through which air may be admitted into the casing and thence into the conduit I.

L is a funnel-shaped tube arranged within the tube K, connected at its lower end with an oil conduit or chamber M, leading to the valve H and communicating with a port a in said valve. This port a connects with a port L, which forms the connecting-passage in the nozzle F.

N is a Valve-stem for the valve H, which passes out through the casing and is connected with a gear-segment O. This segment meshes with a complementary segment I),

float D is normally below the upper end of the nozzle F, but is .above the conduit M and the valve H. As a consequence the oil will normally till the passages and a within the valve H and also the space within the conduit M. The suction of the engine will cause the drawing in of a current of air through the tube K and casing .I into the tube I. A portion of this air-current will strike against the funnel L and will be directed down into the conduit M, striking an air-pressure on the liquid therein, which will cause it to be forced outward through the nozzle F into the air-current in the conduit I. The ejection of the oil will also be assisted by the suction resulting from the movement of the air-current past the nozzle. The quantity of air carbureted will be regulated by an adjustment of the lever Q, which will shift the position of the butterflyvalve S so as to variably restrict the conduit I.v The movement of the lever will through the connection of the gear-segments P and O impart a corresponding rotation to the stem N of the valve H, thereby variably restricting the oil-passage of said valve and controlling the amount of oil ejected from the nozzle.

l/Vhat I claim as my invention is 1. A carbureter comprising an air-suction conduit, an oil-nozzle directed therein and means within said air-conduit for deflecting a portion of the air-current therein upon the oil to produce a propelling pressure thereof.

2. A carbureter comprising an air-suction conduit, an oil-nozzle directed therein and connected with an oil-chamber and an openended conduit within said air-conduit leading to said oil-chamber, whereby a portion of the air-current is directed against 'the oil in said chamber to create a propelling pressure therefor.

3. A carbureter comprising an air-suction conduit, an oil-nozzle directed therein and connected with an oil-chamber, a funnelshaped conduit within said air-conduit and having its contracted end connecting with the oil-chamber whereby a propelling pressure for the oil is created.

4. A carbureter comprising an air-suction conduit havinga return-bend therein,a funnelshaped conduit within said air-casing on the inlet side of said return-bend, an oil-chamber with which said funnel-shaped conduit is connected, an oil-nozzle leading from said chamber and directed into said air-conduit on the opposite side of said return-bend.

A carbureter comprisingI an air-Suction conduit having a return-bend therein, an oilnozzle discharge within said conduit in the direction of the indrawn air-current, and beyond the return-bend, a butterfly-valve within said conduit in the path of the discharge from said nozzle, a plug-valve in said nozzle, intermeshing gears connecting said butterfly-valve andplug-valve,and means to actuate one of said Valves whereby the other is automaticallyoperated to proportionately vary the air and oil.

6. Vicarbureter comprising an oil-casing, a float-controlled oil-inlet valve therefor, an airsuction conduit having a return-bend arranged adjacent to said oil-casing, an oil-discharge nozzle in said conduit on one side of said return-bend and directed in the direction of the travel of air, a conduit connecting said nozzle with said oil-tank, a plug-valve in said conduit, a butterfly-valve in said air-conduit, a common actuating connection for said valves, and a funnel-shaped deiiector in said air-conduit having a lateral connection with said oil-discharge nozzle whereby a propelling air-pressure is placed on said oil and whereby the discharge of oil is proportioned to the flow of air in Said conduit.

In testimony whereof I ailiX my signature in presence of two witnesses.
